BACKGROUNDTo investigate the contributions of CYP2C19 polymorphisms to the various clopidogrel responses tested by thrombelastography (TEG) in Chinese patients with the acute coronary syndrome (ACS).

METHODSPatients were screened prospectively with ACS diagnose and were treated with clopidogrel and aspirin dual antiplatelet therapy. CYP2C19 loss of function (LOF) and gain of function (GOF) genotype, adenosine 5'-diphosphate (ADP)-channel platelet inhibition rate (PIR) tested by TEG and the occurrence of 3-month major adverse cardiovascular events and ischemic events were assessed in 116 patients.

RESULTSHigh on-treatment platelet reactivity (HTPR) prevalence defined by PIR <30% by TEG in ADP-channel was 32.76% (38/116). With respect to the normal wild type, CYP2C19*2, and *3 LOF alleles, and *17 GOF alleles, patients were classified into three metabolism phenotypes: 41.38% were extensive metabolizers (EMs), 56.90% were intermediate metabolizers (IMs), and 1.72% were poor metabolizers (PMs). Of the enrolled patients, 31.47%, 5.17%, and 0.43%, respectively, were carriers of *2, *3, and *17 alleles. The HTPR incidence differed significantly according to CYP2C19 genotypes, accounting for 18.75%, 41.54%, and 100.00% in EMs, IMs, and PMs, respectively. Eighteen (17.24%) ischemic events occurred during the 3-month follow-up, and there was a significant difference in ischemic events between HTPR group and nonhigh on-treatment platelet reactivity group.

CONCLUSIONSGenetic CYP2C19 polymorphisms are relative to the inferior, the antiplatelet activity after clopidogrel admission and may increase the incidence of ischemic events in patients with ACS.

OBJECTIVETo evaluate the incidence of Ketoconazole associated hepatotoxicity and related factor.

METHODSLiterature retrieval was conducted by using multi-databases for meta-analysis on Ketoconazole associated hepatotoxicity. The data were collected with a standardized form. Overall estimation of incidence of hepatotoxicity for specific study type was calculated by using a DerSimonian-Laird random-effects model owing to the substantial differences among the studies.

RESULTSTotally 204 eligible studies were included in the analysis. The incidence of Ketoconazole associated hepatotoxicity was 3.6%-4.2%. The dosage and duration specific subgroup analyses did not show any significant difference among groups, while the age specific subgroup analysis showed the incidence in children and people aged >60 years was 1.4% (95% CI: 0.5%-4.2%) and 3.2% (95% CI: 1.1%-8.7%) respectively. Additionally, the incidence of the hepatotoxicity was higher in people who had oral administration of ketoconazole beyond the provisions of the usage instructions, and the incidence was 5.7% (95% CI: 4.5%-7.2%).

CONCLUSIONKetoconazole associated hepatotoxicity was common. Off-label use might increase the risk of liver damage. Well-designed large sample studies are needed to identify the risk factors in future.

Objective To investigate the relationship between the Apolipoprotein(Apo)A5-1131T>C polymorphism and strokes.Methods Polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP)and polyacrylamide gel eletrophoresis(PAGE)wefe used to analyze the genotypic polymorphism in 327 patients with stroke(including 194 cerebral infarction patients and 133 cerebral hemorrhage patients)and 311 healthy controls.The levels of serum lipids profiles were also measuredby enzymatic methods. Results The frequency of the-1131C allele in cerebral infarction patients was significantly higher than that of the control group(44.1% vs 32.3%,P<0.05),but there was not statisticai difference between cerebral hemorrhage patients and controls on the-1131C allele frequeney(35.4%vs 32.3%,P>0.05).Compared with the noncamers,the C carriers also had a higher triglyceride(TG)levels in stroke group[(1.45±0.77)vs(1.69±1.06)mmol/L,P<0.05],but the total cholesterol(TC),high density lipoprotein cholesterol(HDL-C)and low density lipoprotein cholesterol (LDL-C)levels did not show statistical differences in various genotypes(P>0.05).Unadjusted Logistic regression analysis indicated that TC+CC genotype of A5-1131T>C was significantly associated with the presence of cerebral infarction,but not with hemorrhage stroke.Logistic regression analysis adjustedfor BMI,presence of hypertension or diabetes and HDL-C levels revealed that TC+CC genotype was an independent risk factor for cerebralinfarction(OR=1.932,95%CI:1.057-3.532,P=0.032). Conclusion The ApoA5-1131C allele frequency of the patients with cerebral infarction is significantly higher than controls.ApoA5-1131T>C polymorphism has a significant influence on serum TG levels.The ApoA5-1131T>C variant is associated with an increased susceptibility for ischemic stroke.

OBJECTIVETo study the clinicopathological features and differential diagnoses of mixed epithelial and stromal tumor of the kidney.

METHODSClinical and pathological characteristics of 4 cases of mixed epithelial and stromal tumor of the kidney were studied.

RESULTSThree patients were female and one was male. All patients presented with flank pain and hematuria. Radiologic studies revealed cystic and solid masses involving the kidney. Grossly the tumors had a solid and cyst appearance. Microscopically, the tumors were composed of a mixture of stromal and epithelial elements. The epithelial elements were variable in cell types including cuboidal, hobnail and columnar cells. One case showed Müllerian and intestinal epithelial differentiations. Stromal elements essentially consisted of spindle cells, with thick-walled blood vessels and bands of smooth muscle cells as distinctive features of the tumor. Immunohistochemical staining revealed that the epithelial components were positive for AE1/AE3, whereas the stromal components were positive for ER, PR, and SMA. All patients underwent nephrectomy and were well without evidence of recurrence.

CONCLUSIONSMixed epithelial and stromal tumor of the kidney is a benign neoplasm with distinct histopathological features. It should be distinguished from many other renal neoplasms. Surgical intervention is a preferred therapy.

Purpose of this study was to establish an effective method in vitro to proliferate natural killer T (NKT) cells from umbilical cord blood (UCB) and peripheral blood (PB), and to study their different phenotype. Mononuclear cells (MNC) from UCB and PB were cultured in the presence of IL-2 (100 U/ml), with or without alpha-Galcer. TCR Valpha24 Vbeta11 double positive natural killer T-cells (NKT cells) and their other phenotypes were determined by flow cytometry. The results showed that after expansion for 7 days, TCRValphabeta(+) NKT cells from UCB-MNCs increased by (8.74 +/- 4.37) x 10(2) times as much, but most of them did not express NK1.1 and its TCR Vbeta11(+) was higher than TCR Valpha24(+). After expansion for 14 days, TCR Valphabeta(+) NKT cells from PB-MNCs increased by (3.72 +/- 2.01) x 10(2) times, the expression of NK1.1 was high and its TCR Vbeta11(+) was almost equal to TCR Valpha24(+). It is concluded that human TCR Valpha24 Vbeta11 double positive NKT cells can expand by addition of alpha-Galcer. The proliferation efficiency in UCB-MNCs is greater than that in PB-MNCs. Most of the UCB-NKT is NK1.1(-), while the PB-NKT is NK1.1(+), a new subset of NKT cells.
